Find the domain of the given function.
K(v)= (4v^2-9)/(v^2-v-90)

You can put this solution on YOUR website!
K%28v%29=+%284v%5E2-9%29%2F%28v%5E2-v-90%29
The domain of the function is such that expression in the denominator is non zero
%28v%5E2+-+v+-90%29+%21=+0
%28v-10%29%28v%2B9%29+%21=0
v%21=-9++and+++v%21=10
so the domain of the function is the set of all Real numbers except {-9,10}
i.e. R - {-9,10} where R is the set of Real numbers
